Molybdenum and rhenium carbonyl complexes containing thiolato ligands

“…[1][2][3] Thiolato complexes are of particular relevance in bioinorganic chemistry, [4][5][6] as many enzymes feature metal coordination by the thiolato groups of cysteine residues; in medicine, gold thiolatos are of importance as drugs, particularly in arthritis therapy, [7,8] and volatile molecular thiolatos have been used as starting materials for chemical vapor deposition (CVD) of metal or sulfide layers. [9,10] The behavior of organosulfur metal compounds has been extensively studied and is expected to be similar to those on the surface of catalysts employed in hydrodesulfurization (HDS), a process used to remove sulfur-containing impurities from crude petroleum in order to minimize environment pollution, and the poisoning of the catalysts used for subsequent transformations. [11][12][13][14] Although the mechanism of the catalytic process is still unknown, coordination of the SR group to the metal is believed to be an essential step.…”
